Our engineers have identified a video playback issue with Google Classroom. 😖
The video screen will freeze but the audio track will play without issue. Additionally, there have been issues of the video not being able to be played back or fast forwarded within Google Classroom.
We have identified it to be a Google Drive issue, and have opened a case🕵️♂️ with the Google Drive team so that they can identify the root cause and hope they are able to deploy a fix soon. We assure you, your video(s) are not lost.
In the meantime, please download your videos as a workaround.
